a fine composition ..and a lovely blending of lights and shades and a ghostly appearance on the ceiling.. Sometime back, such a shot appeared in isa's gallery in B/W:above all.
Here the green works well..
Diagonal frame is fantastic..
Salutes dear Francine.
A NICE DAY :)

Yes, I know very well this place.
Really once I did a very similar picture... but I wasn't happy with that photo.
Anyway, you has done a very clever shot with the silhouettes of the people on the glass corridor.
